Taichung decides to postpone launch of MRT Green Line 12/14/2020 01:09 PM CNA file photo Taichung, Dec. 14 (CNA) Commercial operations on the first line of the Taichung mass rapid transit (MRT) system, which were suspended due to a major malfunction during trial runs, will not begin as scheduled on Dec. 19, Taichung Mayor Lu Shiow-yen (盧秀燕) said Monday. The MRT system's Green Line started trial runs Nov. 16, but those were suspended because of a major malfunction on one of the trains at the Taichung High Speed Rail Station terminal on Nov. 21. After an investigation, the train's Japanese manufacturer, Kawasaki Heavy Industries, said the breakdown was caused by a U.S.-made coupling connecting the two-carriage train that broke, according to the system's operator, Taichung Mass Rapid Transit Corp (TMRTC).
